Specification of Letters Patent.

Application filed February I6, 1904. Serial 110 193,895-

To aZZ whom, it may concern:

Be it known that I, WILLIAM W. DINGEE, a citizen of the United States,and a resident of the city and county of Racine, in the State ofWisconsin, have invented certain new and useful Improvements inAutomatic Means for Feeding Liquids, of which the following is a full,clear, and exact description.

This invention has for its object to provide an improved construction ofautomatic means for feeding liquids that is particularly adapted as alubricator of the forced-feed type for traction and like engines and theinvention consists in the features of improvement hereinafter described,illustrated in the drawings, and more particularly pointed out in theclaims at the end of this specification.

My invention is especially adapted as a force-feed lubricator fortraction and like engines and provides a simple construction which maybe mounted on the casing of the governor-controlled valve and beoperated from the governor-shaft.

Figure 1 is a view showing my improved lubricator in side elevation andin position to be driven from the governor-shaft of the engine. Fig. 2is a plan view of the parts shown in Fig. 1. Fig. 3 is a view invertical section on line 3 3 of Fig. 2.

In the accompanying drawings, A designates the governor-valve casing,whichis usually mounted upon the cylinder of the engine, to the head aof which casing leads the governor-valve stem B, that is controlled bysuitable governor mechanism. The specific form of governor mechanismemployed forms no part of the present invention, and in the drawings Ihave illustrated a governor of the wellknown Waters style.

The overnor-shaft C is driven by a suit- .able pu ley c and is mountedin a long bearing 0 the inner end of this governor-shaft being providedwith a bevel gear-wheel C, that meshes with a corresponding bevelgearwheel at at the lower end of the vertical sleeve D of the governor.As the construction and operation of the parts of the governor are wellunderstood, they need not be particularly described.

The governor-shaft C has keyed thereto a worm-s eeve E, that meshes witha wormwheel E, keyed to the shaft F, by which the automatic lubricatorwill be driven. This shaft F is mounted in a long bearin from the topplate G. The to p ate G is bolted, as at a to the cover a of t egovernorvalve chamber A and supports the lubricator chamber or cylinderH, which depends from the top plate. The shaft F is held in properrelation to its bearing-sleeve f by means of a collar f secured to theshaft. U on the shaft F is mounted the worm-sleeve ,whereby thelubricator mechanism will be driven. This worm-sleeve K is preferablyprovided with two reversely-threaded sections 1c and is, arranged at theopposite ends of the sleeve K. The sleeve K is fixed to the shaft F bymeans of a set-screw k that asses through the section k of the sleeveand by means of the screw 762, the inner end of which is adapted toenter holes f in the shaft F, the worm-sleeve K can be fixed at suchposition that either the section is or 7c can be brought into gear withthe worm-wheel M, or the blank space intermediate the sections is and ismay be brought op osite the worm-wheel M. The worm-wheel M is fixed tothe screw-shaft N, that passes through the top plate G and has athreaded portion n, that passes through the correspondingly-threadedupper end 1) of the plunger or piston P of the lubricator. This plungerP carries at its lower end a on leather p, held in place by the nut p ont e reduced and threaded lower end of the plunger. The plunger P isfitted within the cylindrical lower portion h of the lubricatorcasing H,and this casing H is rovided about midway with an offset mout or nozzle7L2, whereby oil will be admitted to the lubricator when it is to befilled. As shown, the upper end of the lubricator feed-shaft N isprovided with a handle S, by means of which the oil may be forced fromthe lower portion h of the lubricator-casing by hand when desired, andby means of which handle also the plunger P of the lubricator may bequickly restored to its initial position, which will be within the upperpart of the casing H at a point slightly above that shown in Fig. 3 ofthe drawings. From the bottom of the lubricator-casing H extends adelivery-pipe T, that will lead to the steam-chest of the engine or toany other oint at which it is desired to deliver the oi As shown,acheckvalve twill be interposed in the delivery-pipe T, so as to preventthe escape of the steam f, rising mouth W.

From the foregoin description the operation of my improve lubricatorwill be seen to be as follows: When the lubricatingchamber is to haveits lower portion filled with oil, the worm-sleeve K will be shiftedlengthwise of the shaft F until the blank portion of the sleeveintermediate the wormsections 7c and k is opposite the worm-wheel M ofthe lubricator feed-shaft. The operator will then by means of the handleS rapidly turn the shaft N until the plunger P is withdrawn to the upperportion of the easing H to a position slightly above that shown in Fig.3 of the drawings. The check-valve .t of the delivery-pipe T beingturned to prevent the admission of steam through the pipe T, oil will bepoured through the filling- -mouth h until the lower portion h of thelubricator-chamber is practically full. The operator will then by meansof the handle S force downward the plunger P until it passes below thefilling-mouth 7L2, after which the valve 13 of the delivery-pipe T willbe turned to open position. The operator may then by hand force down theplunger P sufficiently to cause an initial charge of oil to pass intothe steam-chest of the engine or may at once move the worm-sleeve Kuntil one of its threaded sections k or 7.0 is in engagement with theworm-wheel M. The worm-gearing intermediate the lubricatorfeed shaft Nand the governor drive-shaft C affords a most effective reducing-gear,so that about three thousand or more revolutions of the overnor-shaftare necessary to effect a sing e revolution of the lubricator feed-shaftN. Hence it will be seen that the downward feed of the plun er will bevery slow, and in practice I have ound that a sinle char e of thelubricating-chamber will ast for a out six hours work of the engine.

The object in providing the reversely-arranged worm-threads 7c and k isto enable the lubricator feed-shaft to be driven in the same directionregardless of the direction of travel of the governor drive-shaft C andof the shaft F. This is a feature of importance, particularly intraction-engines, as withsuch class of engines it is necessary thatprov1s1on be made for as effectively lubricating the engine when mediateblank space may be brought oppo- 'site the worm-wheel M. The handle Snot I only serves for restorin the plun er P to the top of the casing Hw en a fres supply of oil is to be delivered to the casing, but alsoenables the feed-shaft N to be quickly actu-- ated by hand in case agreater supply of oil be temporarily desired.

It will be noted that gearing is provided for automatically operatingthe feed-screw of the plunger and that by shifting the wormsleeve K sothat its blank portion is opposite the worm-wheel M this gearing isdisengaged, and the feed-screw may then be operated quickly by hand forretracting the oil-plunger. The handle S, however, cannot be properlyoperated for quick shift of the plunger until the automaticdrive-gearing is disconnected. The worm-gear provides a slow automaticfeed for the plunger, but may be disconnected in the manner described topermit a quick return of the plunger by hand.

The feed-screw n enga es the upper portion of the plunger, an theplunger and screw are of such length that when the plunger reaches thelower end of its movement it is disengaged from the feed-screw, so thatthe continue'dmovement of the screw cannot operate to break any of theparts. The upper portion of the cylinder or chamber H is broken away atits sides, so that the plunger may be readily lifted and again engagewith the screw.

The present invention affords a most effective means for lubricatingthrottle-valves, steam-chests, and cylinders of engines, and while Ihave described What is regarded as the preferred form of the invention Iwish it distinctly understood that the precise details of constructionabove set out may be varied without departure from the spirit of the invention and that features of the invention may be employed without itsadoption as an entirety.

One marked advantage of the present invention is that of gearing thelubricator to the governor drive-shaft, as by this means a most simpleand compact arrangement of parts is ad and the lubricator is sustainedin the most effective and convenient position. So, also, it will be seenthat the inverted cup-leather at the lower end of the piston when raisedto its uppermost position is filled with air, and when the pistonislowered the air thus confined within the cup-leather forms a cushionbetween the piston and the oil to be forced from the cylinder, thusdoing the Work of the air-chamber in an ordinary IIO force-pump. Theexpansion of the cupleather against the side walls of the cylinderrenders unnecessary the use of expensive stuffing-boxes such as havebeen heretofore em loyed.
